Still, one learns. (The moment one stops learning, I contend, is the moment the lid should be closed.)
Some time in the past year or so I observed that death begins when learning ends, which I gather looks at the question from the other direction. Nor is it a matter of mere philosophy; any critter in the wilderness depends for survival on its ability to adapt to a new situation, whole species can be wiped out by failure to adapt.
I didn’t claw my way to the top of the food chain to spend decades using knowledge I only picked up over the course of a few years spent in school.
